Dalam kertas ini kita akan menentukan polisi terbaik bagi masalah penambahan perolehan inventori apabila kadar permintaannya tentu berubah dengan masa secara selanjar untuk sesuatu tempoh yang terhad. Kita tentukan bila dan jumlah kuantitinya untuk setiap kitaran. Kita gunakan prosedur genetik algoritma yang berasaskan kepada prinsipal kewujudan Darwin dan model hamparan di dalam Microsoft Excel Solver. Keputusan berangka dari beberapa contoh menunjukkan kedua-kedua prosedur mampu memberikan penyelesaian yang optimum. Katakunci: Permintaan berubah dengan masa; Genetik algoritma; Model hamparan dan Inventori. This paper addresses the problem of determining the best policy for an inventory replenishment with continuous deterministic time-varying demand over a finite planning horizon. We determine when to replenish and how much for each batch. We propose a genetic algorithm procedure which is based on Darwin's survival of the fittest principle and a method using spreadsheet modelling in Microsoft Excel Solver. Numerical results from our examples showed that both procedures produced optimal solutions reported in the literature. Keywords: Time-Varying Demand; Genetic Algorithm; Spreadsheet Modelling and Inventory.Downloads
